Coherent Awarded Phase 3 of IARPA Resilience Program for High-Energy Rechargeable Lithium-Sulfur Batteries
September 12 2024 - 3:30PM
Coherent Corp. (NYSE: COHR), a leading provider of advanced
engineered materials, announced its selection for Phase 3 of the
Intelligence Advanced Research Projects Activity (IARPA) RESILIENCE
program. The project focuses on the development of high-energy
rechargeable lithium-sulfur (Li-S) batteries. This achievement
follows the company's successful completion of Phase 2 in June
2024. Coherent is one of only two companies advancing to this
critical phase.
The Robust Energy Sources for Intelligence Logistics In Extreme,
Novel, and Challenging Environments (RESILIENCE) program seeks to
develop reliable power sources for applications in extreme and
challenging environments while ensuring secure, domestic supply
chains for battery material. The program is designed to increase
cell energy density by up to 2x and calendar life by up to 10x
beyond the performance of current commercial lithium-ion
batteries.
In Phase 1 of the program, Coherent demonstrated its patented
immobilized chalcogen cathodes in coin cells, achieving exceptional
results. In Phase 2, Coherent successfully scaled-up the technology
to large-format pouch formats. Phase 3 will focus on transitioning
from research and development to the production of pre-commercial,
manufacturable battery samples for rigorous testing and
validation.
“The proprietary Coherent chalcogen immobilization technology is
unlocking the long-sought potential of sulfur as a low-cost,
high-energy cathode material,” said Rob Murano, Senior Director,
Product Development and Commercialization. “Our Li-S technology
delivers exceptional energy density, fast charge/discharge
capabilities, and unprecedented calendar life, paving the way for a
stable and secure battery material supply chain. This achievement
is the culmination of over a decade of dedicated research and
development, positioning us to meet the demands of emerging
applications across multiple sectors.”
Coherent Li-S batteries are built on a strong portfolio of
patents, including innovations in chalcogen immobilization,
advanced electrolytes, and cathode manufacturing. These innovations
enable sulfur cathodes to operate near theoretical capacity with
high cycle stability and efficiency across a broad temperature
range. Additionally, Coherent technology allows for customization
of cathode performance by adjusting the sulfur and selenium
content—maximizing energy storage with higher sulfur content or
enhancing power delivery and reducing charging time with increased
selenium content.
Coherent will execute Phase 3 of the RESILIENCE program under a
12-month, $2.45 million contract with IARPA.
